Mechanism for vVashing-h/laohines; and I dolly shaft and mechanism dohereby declare that the following is a full,

clear, and'eXact description thereof, reference being had to theaccompanying drawand to the letters of reference marked ings, thereon,cation.

This invention relates to an improvement in operating mechanismforwashingmachines and consists of the matters hereafter which form apartof this specifidescrib'ed and more particularly pointed out in theappended claim.

The invention is here shown as applied to the operation of a-washingmachine of the familiar dolly type, consisting of atub having a hingedtop in which is supported a shaft which depends into the tub andwhich isprovided at its lower end with a dolly or dasher adapted for rotary,alternating move:

ment. The operating mechanism is of the lever actuated, high-speed-geartype and includes a prime moving lever fulcrumed to the side of the tuband a fly wheel, together with a mechanism on the one hand for impartingrotary, alternating movement to the on the other hand for imparting acontinuous rotary movement to the fly wheel.

In the drawings: Figure 1 is a view in side elevation of a washingmachine provided with my improved operating mechanism. Fig. 2 is a viewin front elevation thereof. Fig. 3 is a detail plan sectional view, saidsection being indicated vy the line 3-3 of Fig. 1.

Referring now to that embodiment of my invention illustrated in theaccompanying drawings, 5 indicates the tub, 5*, a lid hinged to the topthereof, and 6, the usual upright supporting legs therefor, said tub inthis case providing the support for the operating mechanism. I

8 indicates the dolly or beater which is non-rotatively connected to adolly shaft 9 that is rotatively suspended from the top of the hingedlid 5 of the tub. Said shaft 9 has bearing in a sleeve 10 which projectsthrough a suitable aperture formed in said lid and said sleeve is madeintegral with a plate 1( fixed to the upper surface of the lid. 11indicates a gear fixed tothe upper end of the said shaft 9, and 12indicates a gear case for protecting said gear, said gear case beii rgfixed to the plate 10.

Alternating, rotary movement is impartedto the gear 11 by means of alongitudinally reciprocating bar 13 provided near one end and on onelateral edge with a rack 13' which engages" the gear 11. The rack 13 isheld in engagement with the gear 11 by means ofan angle plate 14attached to the top surface of theli-d 5 and havingbeariirg engagementwith the outer lateral edge of theba-r 13'.- The' bar 13- is pivotallyconnected to the upper end of lever 15 which is fulcrumed intermediateits ends to a bracket} arm 16 attached'to the-"side of the tub body nearits bottonr.

17 indicates a prime mover in the form of a hand lever which isfulcrumed'intermediate its ends and nearer its lower end to a bracketarm- 18 secured to the side of the tub body.

The levers 15 and 17 are arranged so as to swing in parallel verticalplanes and the bracket arms 16 and 18 are made integral with a baseplate 19 which is attached to the tub body near its bottom edge, in anysuitable manner.

Fixed to the bottom of the tub body 5 and near the center thereof, is adepending bracket member 20. Said bracket member is provided withhorizontally extending, laterally spaced studs 21, 22.

23 indicates a vertically arranged fly wheel rotatively mounted on thestud 22. Said fly 23 is provided with a toothed hub 24 and the teeth ofsaid hub are engaged by a vertically arranged large gear wheel 25 whichis rotatively mounted on the stud 21. The gear wheel 25 is provided witha crank pin 26 which is operatively connected by a pitman rod 27 to thebottom end of the lever 15.

28 indicates a link which is pivotally connected at one end to thebottom end of the prime moving lever 17 and at the other end to thepitman rod 27 at a point intermediate 28, the pitman 27, the gear wheel25 and the rack bar 13, impart a rotary, alternating movement to thedolly shaft 19 and at the sametime, said lever will through the linktoothed hub 24:, impart a continuous rotary motion to the fly wheel 23.

WVhen it is desired to swing the hinged lid,

5 to an open position, the rack bar '13 is swung vertically upward aboutits pivotal connection with the lever out of the way,

thus permitting said lid to be opened.

It will be noted that by the gearing described, an increased leverage isprovided for operating the mechanism which actuates understood thatthe'invention is not to be in the appended claim. I

I claim as my invention:

An operating mechanism for washing machines and the like, comprising incombinalimited thereto except as may be pointed'out tion with a supporthaving an operating shaft rotatively carried thereby, a prime movinglever fulcrumed to the side of said an oscillatory movement of saidlever, said means comprlslng a crank'pln on sald gear, a

pitman rod pivotally connected atone end-t0; said crank pin and havingits opposite end pivotally connected to said second mentioned lever anda link pivotally oonnectedatone end to said pitman rod at'a pointintermediatethe ends thereof and at its opposite end tosaid prime movinglever.
